With automatic weighing machines, which serve for weighing fine powdery,-eas1ly fiowing material, it is of greatest importance that no material can escape outwardly .by the joints between the bottom fiap and the edges of the outlet of the receptacle, particularly at the commencement of filling the weighing retom flap so well that it is perfectly air-tight.

Such a good closure of the material receptacle is the more difficult since now-a-days cement, carbon-dust, and so on, is ground up to utmost fineness, and in most cases is weighed while still hot.

By the present invention the escape of the material outwardly by the joints of the bottom flap is prevented independent of the fineness of the material, and even when it is in a hot state so that the weighing can be carried out without losses. This result is secured by the present invention in this manner that the entering material is prevented to fall down in a vertical line by inclined baffle plates, guiding the material towards the side walls of the receptacle, and moreover by this that in the lower part of the receptacle preferably yielding or elastic guide plates are so arranged that the material falling down along the side walls is deflected away from the joint between the bottom fiap and the walls of the receptacle and directed towards the center of the bottom. 7

By thus guiding the material laterally towards the side walls of the receptacle, the drop is considerably weakened, and-then the deflection of the material away from the joints by guide plates is the more effective, so that an escape of the material outwardly is completely avoided.

Reference is had to the accompanying drawing in which the construction of a weighing receptacle is shown by way of example.- I Within the'upper part of the receptacle a two inclined bafile platesb are fixedly arranged contacting on top, for instance, in'the manner of a saddle or of a roof. The entering material falling vertically down is divided by the baffle plates 1) into two streams, each stream being directed by one of the baffie plates against the next wall of the recep- I in any desired manner either by welding. or by riveting. With their lower ends the plates 0 are arranged at a distance from the joint be-- tween the bottom flap and the walls of the receptacle. Owing to'the pressure exerted by the material the yielding plates 0 will bear on the bottom flap 0!, thus forming even here a close fit.

By the fact that the material first strikes against the said walls and then slides along the plates 0 it is given the tendency to move towards the center of the receptacle, as is indicated in the drawings by arrows. The two streams coming from the sides meet at the center and direct the entrained air upwardly, and therefore can no more exert any lateral pressure.

The yielding guide plates 0 moreover have the object to counteract the inconvenient pressure on filling the receptacle, and by this pressure of the material against the bottom 0? the plates bear against the bottom and thus also prevent any escape of the material between the bottom flap and the walls of the receptacle. It is therefore evident, that the arrangement of the inclined plates Z) and of the guide plates 0 secures in a most simple manner a very good closure.

The length of the plates 6 depends on the size of the receptacle.

I claim 1. A receptacle for the material of automatic Weighing machines comprising inclined plates within the upper partof the receptacle and guide platesv in the lower part of the 5 receptacle hearing ,with their upper end against the walls and extending from here downwardly and inwardly to deflect the material striking-the said .wallstowards-the centerin the lower part of the receptacle 2.

In testimony whereof I have signed my name to this-specification.
